Abstract (en)
[origin: GB2432398A] The engine has a cylinder 10 having a cylinder head 12 and a side wall 16 extending away from the cylinder head 12. An inlet port 21 and an exhaust port 22 are defined in the side wall 16. A sleeve valve 13 slides axially along the cylinder 10 while simultaneously rotating about the axis of the cylinder 10. The sleeve valve 13 has sleeve ports 23 which move into and out of alignment with the inlet 21 and exhaust 22 ports to thereby open and close the ports 21,22. A piston 14 reciprocates within the sleeve valve 13 and within the cylinder 10 to define a combustion chamber. A sleeve valve driving mechanism 24, 25, 26, 27, 28, 29, 30, 31 drives the sleeve valve 13 to slide axially along and rotate in the cylinder 10 in timed relationship with reciprocation of the piston 14 in the cylinder 10. The sleeve valve 13 is driven between two extreme positions in each stroke and the sleeve driving mechanism 24,25,26,27,28,29,30,31 is operable to vary in locations the two extreme positions, thus varying the valve timing.
